In recent years, the problem of dew condensation in greenhouses has become an important factor in the reduction of crop yield and quality in greenhouses for high-density vegetables, flowers and seedlings.
In recent years, the industry has done a lot of work in this area, such as adopting non-drip film and adjusting the structural parameters of the greenhouse, which have achieved certain results. However, the key "drip line" problem focused on the frame cannot be solved, and the circular steel pipe has nothing to do with it.
The cold-formed steel is designed as a specific profile, so that the dew condensation on the membrane can flow into the curved parts on both sides and then be discharged along the frame. For multi-span greenhouses with complex structures, the dew condensation on the sub-beam can also flow into the main beam and then be discharged.
This type of profile can greatly alleviate the damage to crops caused by condensation water droplets in the greenhouse, and has great significance for improving the quality and yield of crops in the greenhouse. The unique arched purlin structure effectively solves the dew phenomenon caused by the temperature difference between the inside and outside of the greenhouse, and can effectively solve the problem of condensation in the greenhouse in winter.
In fact, the anti-condensation function design of cold-formed steel is not limited to a few profiles, and various functional sections can be designed according to the specific use position.
